It will be hard for him to beat Yashin or Spezza, but if he even slots in at #3 in franchise history, which I expect him to, we will have done very well.
Funny you should say he'll have a hard time beating Spezza.
Spezza when he turned 21:
76 points in 111 games, good for 56 point pace.
Stutzle 2 months shy of turing 21:
100 in 146 games, good for 56 point pace.
Presumably, Stutzle will build a lead in next 2 months, plus his total is dragged down by having started in NHL sooner. Unlike Spezza, Stutzle will also get his 22 y/o season in the NHL.
Due to injuries and lock out Spezza only played 11 seasons and 686 games for Ottawa.
Stutzle has already played 146 and is under contract for another 718.
If Stutzle can stay healthy, I think he can easily surpass Spezza overall. Spezza's best season ever: 108 point pace, will be difficult to reach. It remains to be seen whether Stutzle can reach Spezza's peak, but I'm very confident he will produce more as a Senator than Spezza did.
